Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a method, apparatus, vehicle, and storage medium for degassing a vehicle cooling system. Background Technology
[0002] In automotive cooling systems, coolant circulation is crucial for maintaining the normal operating temperature of the engine and electric drive system. However, during coolant changes or system operation, air can infiltrate the system. This air encroaches on the space that should have been used for coolant flow, leading to decreased cooling efficiency and reduced heat exchange. Some components, such as the engine block walls and electronic control components in new energy vehicles, already have relatively high temperatures. The temperature rise rate of these electronic control components in new energy vehicles is extremely rapid, and these localized high-temperature points can easily reach the boiling point of the coolant, causing localized boiling and threatening vehicle safety. Since electronic control components have built-in temperature sensors, if the localized boiling point is located close to the coolant temperature sensor, it may cause false alarms, leading to the failure of the entire powertrain. Localized boiling in the engine can further spread and affect power output, posing a safety hazard and potential power failure. Because the entire cooling system is closed and invisible, there is a lack of effective means to monitor air content, making it difficult to detect and remove air in a timely manner. This problem is particularly pronounced in systems that use natural top-up methods for coolant changes.
[0003] In automotive cooling systems, the presence of air can severely affect cooling efficiency, especially under high temperature or high load conditions. The presence of air can lead to localized boiling, which not only reduces the heat transfer capacity of the coolant but also accelerates the wear of related components and may even cause malfunctions.
[0004] In related technologies, the degassing control device is connected to the coolant circulation device. The degassing control device controls the switching between the first circulation loop and the second circulation loop, thereby enabling free switching between the first circulation loop and the second circulation loop in the fuel cell cooling system. This ensures that the coolant can circulate in the first circulation loop and the second circulation loop at room temperature, so as to degas the fuel cell cooling system.
[0005] However, in related technologies, when the vehicle is powered on, the two circulations are degassed in series by switching valves in the cooling system. This method cannot actively degassed the cooling system according to the actual operating conditions, resulting in low degassed efficiency and reduced applicability and accuracy of the cooling system's degassed function, which urgently needs to be addressed.

[0031] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0039] The following description, with reference to the accompanying drawings, outlines a degassing method, apparatus, vehicle, and storage medium for a vehicle cooling system according to embodiments of this application. Addressing the issues raised in the background section regarding the related technologies where degassing is achieved by switching valves in the cooling system to connect two loops in series, the system cannot actively degas according to actual operating conditions, resulting in low degassing efficiency and reduced applicability and accuracy of the degassing process. This application provides a degassing method for a vehicle cooling system. In this method, when the actual coolant conductivity of the cooling system is detected to be less than a certain conductivity threshold, the cooling system is controlled to enter a degassing mode. Degassing actions are generated based on the target operating conditions of the cooling system and the actual coolant conductivity, effectively improving the degassing efficiency and enhancing the applicability and accuracy of the degassing process. This solves the problems in the related technologies where degassing is achieved by switching valves in the cooling system to connect two loops in series, the system cannot actively degas according to actual operating conditions, resulting in low degassing efficiency and reduced applicability and accuracy of the degassing process.
[0040] like Figure 1 As shown in the embodiment of this application, a degassing system for a vehicle cooling system is established. This degassing system includes an electric water pump 1, electric water pump ECP2, electric water pump ECP3, electric water pump ECP4, a four-way valve ECV1, a three-way valve ECV1, a PTC heater, a dual-mode heat exchanger, a condenser, an evaporator, a motor circulation system, an engine circulation system, and a battery circulation system. Due to layout and cost considerations, the heater circulation and battery circulation systems do not have separate degassing pipes (the degassing pipes are represented by the black dotted lines). However, if there is gas in the battery or heater circulation system, it will affect the system operation. The specific degassing solution involves switching the state of the four-way valve to achieve degassing. Furthermore, by adding conductivity sensors to the heater circulation and battery circulation systems, the system can actively determine whether degassing is needed. Table 1 shows the state table of the four-way valve, as detailed below:
[0041] Table 1
[0042]
[0043] This system, through the application of pumps and valves, can eliminate the need for degassing pipes and related designs in some circulation cycles, directly achieving the degassing function using only the pumps and valves. Degassing is typically used during vehicle startup, coolant addition or replacement, and when the system is about to overheat and fail due to excessively high water temperature. The degassing procedure in this system effectively removes air through built-in degassing devices, such as vacuum pumps or pressure regulating valves. The intelligent control mechanism is the core of this program, including but not limited to sensor data processing, decision logic, activation and control of the degassing equipment, and system status feedback and adjustment. The key advantage of this mechanism lies in its high degree of automation and intelligence, capable of responding to the real-time status of the cooling system and automatically executing degassing operations without manual intervention, thereby improving system reliability and maintenance efficiency.
[0044] Specifically, Figure 2 This is a schematic flowchart illustrating a degassing method for a vehicle cooling system provided in an embodiment of this application.
[0045] like Figure 2 As shown, the degassing method for the vehicle's cooling system includes the following steps:
[0046] In step S201, the actual coolant conductivity of the cooling system is obtained, and it is detected whether the actual coolant conductivity is less than a preset conductivity threshold.
[0047] In this embodiment, the actual conductivity of the coolant is the ratio of coolant to air; the preset conductivity threshold is the baseline value of coolant conductivity in the absence of air, for example, the baseline value can be set to ≥99%. The preset conductivity threshold can be set by those skilled in the art according to the actual situation, and is not specifically limited here.
[0048] It is understood that the embodiments of this application can obtain the actual coolant conductivity of the cooling system. For example, the embodiments of this application can install conductivity sensors at key locations in the cooling system, such as in circulation systems that do not have degassing functions, to monitor the coolant conductivity in real time. The microprocessor receives the data from the conductivity sensor, analyzes the changes in the actual coolant conductivity, and detects whether the actual coolant conductivity is less than the conductivity threshold, effectively improving the feasibility of degassing in the cooling system.
[0049] Therefore, the embodiments of this application can integrate a conductivity sensor into the cooling system to monitor the changes in the conductivity of the coolant in real time, thereby accurately determining the air content in the cooling system. Since the conductivity of air is much lower than that of coolant, the accumulation of air can be quickly identified by comparing the changes in the conductivity of the coolant.
[0050] In one embodiment of this application, obtaining the actual coolant conductivity of the cooling system includes: determining the actual coolant temperature of the cooling system; and determining the actual coolant conductivity corresponding to the actual coolant temperature using a target coolant conductivity curve.
[0051] In this embodiment, the target coolant conductivity curve is a curve showing the change of coolant conductivity with coolant temperature, which can be calibrated and tested according to different coolant specifications.
[0052] In actual implementation, such as Figure 3 As shown, since the conductivity of the coolant also changes with the actual coolant temperature, this embodiment of the application can measure the actual coolant temperature of the cooling system by one or more temperature sensors on the engine coolant path. Based on the above-mentioned coolant conductivity curve, the actual coolant conductivity corresponding to the actual coolant temperature can be determined, thereby determining whether the cooling system needs to be degassed, effectively improving the accuracy of degassed cooling system.
[0053] For example, such as Figure 3 As shown, when the actual coolant temperature is below 100℃, the lower the actual coolant temperature, the faster the rate of change in coolant conductivity as the temperature rises. The higher the temperature, the faster the rate of change in conductivity. For example, at a normal temperature of around 25℃, the conductivity of coolant increases by about 4% for every 1℃ increase in temperature. However, at 100℃ or higher, the conductivity only increases by 1% for every 1℃ increase in temperature. The operating temperature range of coolant in a vehicle's cooling system is generally -40℃ to 135℃. Therefore, the specific changes in coolant conductivity need to be calibrated and tested according to different coolant specifications.
[0054] In step S202, when the actual conductivity of the coolant is detected to be less than the preset conductivity threshold, the cooling system is controlled to enter the degassing mode to determine the target operating condition of the cooling system.
[0055] In the embodiments of this application, the target operating condition is a normal operating condition or an extreme operating condition.
[0056] It is understood that, in the embodiments of this application, when the actual conductivity of the coolant is detected to be less than the conductivity threshold, it indicates that there is air in the cooling system. The degassing procedure can be initiated, the cooling system can be controlled to enter the degassing mode, the target operating condition of the cooling system in the following steps can be determined, the risk of local boiling can be avoided, and the overall efficiency and stability of the cooling system can be significantly improved.
[0057] In one embodiment of this application, determining the target operating condition of the cooling system includes: acquiring the vehicle's total load and the actual ambient temperature; and determining the target operating condition of the cooling system based on the vehicle load and the actual ambient temperature.
[0058] For example, such as Figure 3 As shown, the embodiments of this application can obtain the vehicle's total load, that is, the total load borne by the vehicle during driving and the actual ambient temperature. For example, when the total load borne by the vehicle is low and the external ambient temperature is normal, it can be determined that the cooling system is in normal operating condition. When the total load borne by the vehicle is high and the external ambient temperature is high or low, it can be determined that the cooling system is in extreme operating condition, effectively improving the intelligence of the cooling system's degassing.
[0059] In step S203, the degassing action of the cooling system is generated based on the target operating conditions and the actual conductivity of the coolant.
[0060] It is understood that the embodiments of this application can generate the degassing action of the cooling system according to the target operating conditions and the actual conductivity of the coolant, for example, such as Figure 3 As shown, the embodiments of this application can generate a degassing action for the cooling system when the cooling system is under normal operating conditions or under extreme operating conditions and degassing is required. For example, the degassing program can be started and run through the degassing device built into the cooling system, which effectively improves the degassing efficiency of the cooling system and ensures the efficient and stable operation of the cooling system.
[0061] Optionally, in one embodiment of this application, generating a degassing action of the cooling system based on the target operating condition and the actual coolant conductivity includes: when the target operating condition is a first target operating condition, determining whether the actual coolant conductivity is less than or equal to a first preset conductivity; if the actual coolant conductivity is less than or equal to the first preset conductivity, generating a degassing action of the cooling system; otherwise, not generating a degassing action.
[0062] For example, such as Figure 3 As shown, the target operating condition in this application embodiment is the first target operating condition, i.e., the normal operating condition. For example, when the total load on the vehicle is low and the external ambient temperature of the vehicle is 25°C, it can be determined whether the actual coolant conductivity is less than or equal to the first conductivity. For example, if the actual coolant conductivity is 89%, which is less than the first conductivity of 90%, it is determined that the cooling system needs to be degassed. In this application example, the degasing program of the cooling system can be started, the state of the four-way valve can be adjusted, and degasing can be performed in series through the motor or engine circulation. That is, the degasing program uses the degasing device built into the cooling system, such as the water pump, to increase the turbulence of the coolant by the high-speed operation of the water pump, and extract the air in the cooling system until the actual coolant conductivity is restored to near the conductivity reference value (≥99%), indicating that the air in the cooling system has been basically removed. If the actual coolant conductivity is 91%, which is greater than the first conductivity of 90%, it is determined that the cooling system does not need to be degassed, and no degasing action is generated, which effectively improves the accuracy of the cooling system degasing.
[0063] Optionally, in one embodiment of this application, generating a degassing action of the cooling system based on the target operating condition and the actual coolant conductivity includes: when the target operating condition is a second target operating condition, determining whether the actual coolant conductivity is less than or equal to a second preset conductivity; if the actual coolant conductivity is less than or equal to the second preset conductivity, generating a degassing action of the cooling system, otherwise not generating a degassing action, wherein the second preset conductivity is greater than the first preset conductivity.
[0064] For example, such as Figure 3 As shown, the target operating condition in this application embodiment is the second target operating condition, i.e., the extreme operating condition, such as when the total load on the vehicle is high and the cooling system water temperature is high, or when driving is intense and there is a risk of temperature fluctuations. It can be determined whether the actual coolant conductivity is less than or equal to the second conductivity. For example, if the actual coolant conductivity is 92%, which is less than the second conductivity of 95%, it is determined that the cooling system needs to be degassed. In this application example, the degasing program of the cooling system can be started, the state of the four-way valve can be adjusted, and degasing can be performed in series through the motor or engine circulation. That is, the degasing program uses the degasing device built into the cooling system, such as the water pump, to increase the turbulence of the coolant through the high-speed operation of the water pump, thereby extracting the air in the cooling system until the actual coolant conductivity is restored to near the conductivity reference value (≥99%), indicating that the air in the cooling system has been basically removed. If the actual coolant conductivity is 96%, which is greater than the second conductivity of 95%, it is determined that the cooling system does not need to be degassed, and no degasing action is generated, which effectively improves the accuracy of the cooling system degasing.
[0065] Therefore, by continuously monitoring changes in the conductivity of the coolant, the cooling system can promptly and accurately identify air accumulation, ensuring long-term stable operation of the cooling system and enhancing the reliability of the entire automotive cooling system.
[0066] In some embodiments, the present application embodiments can also continuously monitor changes in the conductivity of the coolant to assess the overall health of the cooling system, and issue voice and pop-up warnings when the air content exceeds a certain threshold, prompting the driver or maintenance personnel to pay attention to the status of the cooling system, avoiding a decrease in cooling efficiency due to air accumulation, thereby protecting the engine and other critical components from damage.
[0067] The degassing method for a vehicle cooling system proposed in this application can control the cooling system to enter a degassing mode when the actual coolant conductivity of the cooling system is detected to be less than a certain conductivity threshold. The degassing action of the cooling system is generated based on the target operating condition of the cooling system and the actual coolant conductivity, effectively improving the degassing efficiency and enhancing the applicability and accuracy of the cooling system's degassing process. This solves the problems in related technologies where degassing is performed by switching valves in the cooling system to connect two circulation loops in series, which fails to actively degas the cooling system according to actual operating conditions, resulting in low degassing efficiency and reduced applicability and accuracy of the cooling system's degassing process.
[0068] Next, the degassing device for a vehicle cooling system according to an embodiment of this application is described with reference to the accompanying drawings.

[0071] Specifically, the acquisition module 100 is used to acquire the actual coolant conductivity of the cooling system and detect whether the actual coolant conductivity is less than a preset conductivity threshold.
[0072] The determination module 200 is used to control the cooling system to enter the degassing mode when the actual conductivity of the coolant is detected to be less than the preset conductivity threshold, and to determine the target operating condition of the cooling system.

[0075] The first determining unit is used to determine the actual coolant temperature of the cooling system.

[0080] Optionally, in one embodiment of this application, the generation module 300 includes: a first judgment unit and a first processing unit.
[0081] The first judgment unit is used to determine whether the actual coolant conductivity is less than or equal to the first preset conductivity when the target operating condition is the first target operating condition.
[0082] The first processing unit is configured to generate a degassing action for the cooling system if the actual conductivity of the coolant is less than or equal to a first preset conductivity, and not generate a degassing action otherwise.
[0083] Optionally, in one embodiment of this application, the generation module 300 includes: a second judgment unit and a second processing unit.
[0084] The second judgment unit is used to determine whether the actual coolant conductivity is less than or equal to the second preset conductivity when the target operating condition is the second target operating condition.
[0085] The second processing unit is used to generate a degassing action of the cooling system if the actual coolant conductivity is less than or equal to a second preset conductivity, and not to generate a degassing action otherwise, wherein the second preset conductivity is greater than the first preset conductivity.
[0086] It should be noted that the foregoing explanation of the degassing method embodiment for the vehicle cooling system also applies to the degassing device of the vehicle cooling system in this embodiment, and will not be repeated here.
